Here is a workflow:
1. I have a VM with 2 disks - One is a OS disk and one is a Data Disk (Persistent Disk)
2. I mount the Data disk to the VM and i use ADE Encryption on it using AzureDisEncryptionForLinux VM extension. The key is stored in Azure Keyvault.
3. Later the VM is being replaced by another VM. THe disk is unmounted from the old vm so it is now trying to be attached to the new VM. However It fails to be mounted because it is a LUKS file type.
My question is do we have to decrypt the disk before detaching from the old VM and mounting ot the new VM or is there a way to mount an already encrypted disk (done via ADE and key in Keyvault) to an new VM ?
